In addition, he published an account of his sixty years of playing recreational baseball entitled Innings. Mike Robertson has been writing on one form or another since he was in high school, his efforts at brief composition and poetry precipitating a life long ambition. He is retired and lived in profound anonymity in Ottawa, Canada.
